It isn't easy to shift your perspective. It would feel so much better if the other person would change. That person that doesn't align with your values. That person who's causing you all this pain. That person who's a disaster to work with.
But that won't happen. Ever. And it's important that you see that as fact. And we all know we cannot change facts. Wanting to fix that person is futile, and that realization is powerful.
That is the first stop in shifting your perspective. Once you do this, you will feel empowered. You will get what you need. You will expand, and your world will expand.
